very new to voip, need assistance for understanding for an office to implement voip.
currently using Linksys ADSL gatewary router, this acts as DHCP, in the network range 192.168.1.x, Has 2 switches not supporting VLANs.
VOIP vendor suggested using HP procurve L2 switch (2 of them). they will configure 2 VLANs, one for data, one for voice on the HP switches. they suggested using their PABX as DHCP.
- if we still want to use back our current router as DHCP, what are the configuration that we need to do such that the voip and data works?
- is it advisable to use their PABX acting as DHCP?
- they suggested to have VPN access to troubleshoot, is this advisable and common for voip vendors to have this access?
